We've learned from experience that when Samsung drops some Note 3 kernel source, the update is only a few days away. This time the Note 3 on T-Mobile is in Samsung's sights as the KitKat code has just been uploaded to Samsung's open source page.

The Galaxy S4 on AT&T started getting its KitKat update today, but the Note 3 is still on the waiting list. Some users were excited to see an OTA notification pop up on Samsung's latest phablet only to have their hopes crushed by what turns out to be another build of Android 4.3.

The kernel source was posted just the other day, which usually signals an update is right around the corner. Indeed, here comes KitKat for the Galaxy Note 3 on Sprint. The 503.6MB OTA download includes a few small tweaks to TouchWiz with Android 4.4.

Samsung's advertising has been somewhat hit or miss lately, ranging from pretty decent scifi ads for the Galaxy Gear to cringe-worthy infomercials for the same product. But it looks like there's been something of a shift in the company's promotional direction, or at least in the way that it responds to Apple's sometimes hyperbolic TV ads. Check out this new one-minute spot for the Galaxy TabPRO 10.1.

The ad plays up the TabPRO's high-resolution screen with a better aspect ratio for movies versus the iPad Air, plus its ability to fit multiple apps on the screen at once, which has been a staple of TouchWiz for a while.

Samsung has updated its open source pages with kernel source for the Sprint version of the Galaxy Note 3, but this isn't just any update. You can now download the long-awaited KitKat source for Samsung's phablet on Sprint. If we take a lesson from recent history, the OTA could be announced as soon as tomorrow.

Samsung has been very cautious in rolling out its KitKat update thus far, with even most Galaxy S4 owners still waiting around on Jelly Bean. This doesn't even take into account all the millions of other Galaxy smartphones and tablets that often take a backseat to the company's flagship. Yet Samsung has now provided a list of all the devices it intends to bump up to Android 4.4.2 before it's all said and done.

Most custom ROMs require separate builds for separate carrier variants - one for an international model, one for an AT&T model, one for a Verizon model, and so on. CyanogenMod is trying to consolidate some of its most popular builds so that a single ROM ZIP file will work across several various device variants. Last month the CM team combined three HTC One builds, and today they're doing the same for Samsung's Galaxy S III, Galaxy S4, and Galaxy Note 3.

Sprint has been marketing push-to-talk functionality (a walkie-talkie style function that's popular with business users) since long before Android came into being. Though the feature isn't nearly as common as it once was, Sprint seems ready to keep it going with an update to the official Android app. The Direct Connect service is now compatible with a handful of new phones, most notably headliners like the Galaxy S4, Galaxy Note 3, and LG G2.

An Android 4.4 update has been hitting Galaxy Note 3s all over the world, and while some people who have yet to receive it may feel a bit envious, there are benefits to waiting. Some users have reported being unable to use third-party flip covers that trigger a special lockscreen when closed. Following the upgrade to KitKat, only Samsung's official products, which contain a special identification chip, would work. Now Ars Technica has received a statement from Samsung acknowledging the issue as a "bug" and announcing a future OTA update that will return functionality to third-party accessories.
